How to force a host to not send a broadcast for an IP address in its own subnet?

arp

For a LAN, instead of a switch, I have built a topology where each machine is connected to a router. Each host is assigned an IP address from 10/8. Here are the interface details:

Lets say I ping 10.16.0.3 from this host. The routing table of 10.16.0.2 has been configured to use the router (10.16.0.1) as the default gateway. But since the destination IP address (10.16.0.3) is in the same subnet it sends out an ARP broadcast. I want to disable this behavior of sending an ARP broadcast and instead force it to use the routing table. How do I accomplish this?
